Second, the anti-corrosion treatment of copper clad aluminum buttons The basic method of anti-corrosion copper is to use the method of micro acid polishing to make the surface of H62 brass show its brightness close to 18K gold. The protective film is then immersed or sprayed on the surface with a repeated coating method. The bottom layer of the impregnated paint is a paint type with good sealing performance to improve its protective performance; the sprayed part requires the use of a paint with high hardness in order to improve the abrasion resistance of the paint film and prolong its use time, thereby ensuring the long-term use of the buttons.
